Dual-Energy CT Pulmonary Angiography: Quantification of Disease Burden and Impact on Management

The objective of this article is to summarize these recent developments and discuss the appropriate use of DE-CTPA post-processing applications.Recent FindingsDE-CTPA post-processing applications enable reconstruction of virtual monoenergetic images (VMI) and color-coded iodine-perfusion maps to increase contrast conditions and visualize lung perfusion defects in case of embolic occlusion of pulmonary arteries. Both techniques revealed a superior diagnostic performance for the detection of pulmonary emboli and assessment of the pulmonary perfusion compared to the standard image reconstructions.SummaryDE-CTPA is a well-established method for excluding or diagnosing PE. Continued developments in DE-CTPA post-processing techniques improve patient management and allow for a quantification of disease burden.
